Secondary Structure, a Missing Component of Sequence-Based Minimotif Definitions
A. Images of 32 secondary structures. The structure, chain, and residue range for each type of secondary structure are shown. B. Bar graph showing the number of occurrences of xYxN sequence matches from the PDB in each type of secondary structure. Unfilled bar indicates the correct structure of known ligands. Arrow indicates the structure of the known Grb2 ligand.
